AttributeError: 'AxesSubplot' object has no attribute 'set_theta_zero_location'

I'm running astroplan.__version__ = '0.8' and when running the tutorial summer_triangle-3.py I get the error below:

---> 35 plot_sky(altair, subaru, start, style_kwargs=altair_style)
     36 plot_sky(vega, subaru, start)
     37 plot_sky(deneb, subaru, start, style_kwargs=deneb_style)

That error happens with astropy.__version__ = '5.1'

Updating to astropy.__version__ = '6.1' solves the issue

I don't think closing this issue as it is is a good idea:

• either astroplan >= 0.8 should require astropy >= 6.1
• or there should be a try/except clause which tries to use the new astropy API version for this operation and in case of this specific AttributeError should revert to the pre 6.1 version
